FOOD PRODUCT.

No Drawing.

To all whom it may concern: 7 Be it known that I, CECIL O. PHILLIPS, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Food Products; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved food product or stock food comprising cottonseed meal and calcium chloride intimately combined with each other.

Cottonseed meal is largely used for feed ing purposes, but its use for certain purposes, such as for feeding hogs, horses. calves and lambs is limited or precluded by the toxic effect of the meal, which may prove fatal in case of continued and prolonged feeding.

i The improved stock food or food product of the present invention possesses advantages over ordinary cottonseed meal, such as increased feeding value, decreased toxicity, less objectionable after effects, or even substantial elimination of objectionable after effects, etc. i

The improved food product of the present invention is made by incorporating calcium chloride in the cottonseed meats during the regular method of manutacturinc cottonseed meal, or by incorporating calcium chloride in cottonseed meal after the removal of cottoi'isecd oil, substantially set forth.

The treatment of the cottonseed with the calcium chloride solution, and the incorporation or combination of; the solution therewith can be carried out in dilferent ways.

The cottonseed meats, prior to the cooking and expression of oil therefrom, can be intimately combined with the calcium chloride solution, for example, by spraying the solu' tion upon the meats and intimately mixing the solution therewith, and then subjecting the treated meats to a cooking operation, subsequently pressing the oil from the cooked meats, and breaking up and grinding the pressed calre in the usual way. This method of treatment has the advantage that the oil extraction is inn iroved by the calcium chloride treatment prior to the cooking and mowing oi iorui'ious. while the calcium chloride solution owls upon and is intimately Specification of Letters Patent.

combined with the substance of the resultmg meal, during the cooking operation.

nstead of treating the cottonseed meats with the calcium chloride solution prior to the cooking operation, the cooked meats may be treated and intimately combined there with prior to the pressin operation, and, in this case, the calcium eh oride solution will have an opportunity of acting upon and combining with the hot meats during'the pressing operation.

According to another method of procedure, the cottonseed meal, after the cooking and pressing operations, is intimately" treated and combined; with "the calcium chloride solution. The press cake can thus be crushed in the usual cake breaker and then ground to form cottonseed meal, and the cottonseed meal can then be treated and intimately combined with the calcium chloride solution. One advantageous method of doing this is to supply the calcium chloride solution in the form of a spray or mist, bymeans of suitable atomizing nozzles, into fallingstreams of the cottonseed meal, and then collecting and further mixing the treated meal. The meal can be supplied by means of a conveyor having a perforated bottom through which the meal falls in a series of fine streams, and the calcium chloride solution can be supplied under pressure and in regulated amount to an atomizingnozzle or a series of nozzles so arranged as to give an intimate distribution of the solution throughout the falling streams of the meal. The meal can then be collected and Further mixed in a suitable conveyor and then conveyed to the place of storage for further use.

The calcium chloride solution can be made up in the form of a stock solution and sup plied in regulated amount to the atomizing nozzles. The solutions can also vary somewhat in their calcium chloride content, and the amount of calcium chloride incorporated with the meal, as well as the amount of rater added with the calcium chloride, can be varied and regulated to give a meal of regulated calcium chloride and moisture content. A strong or saturated calcium chloride solution is usually preferable, for example. a solution of 30 Be. to 40 Be. The amount of the solution incorporated with the meal may, for example, be such as will give about 1% calcium chloride in the final product.

For eiiample, a solution oi about Be. can be supplied under a pressure of 2.5 lbs.

' r s (in. to anatomizin nozzle and in corporated with the cotton-seed meal, in the manner above described, in the proportion of about 45 gals. of solution containing about 115 lbs. of actual calcium chloride to aboutllflfllllbs. ofmeal, so that the resulting meal will contain about? 1%ofi calcium chloride. A larger or smaller amount of calcium chloride: can he intimately incorporated with the meal in a similar manner, by regulating the strength oft'he calcium ehloladen-sodas well as the amount: of theselution.

The treatment of the meal with the calcium chloride; solution can advantageously be carried on as a. continuous operation by treating the meal as it flows contimiouslyfrom the grinder on its Way to its place of storage or packaging, anditlre mate of flow ofthe meal the strength and amount of the: calcium; chloride soliwioni can be suitably regulated, by. autmnatic meams or otherwise;- togiwela substantially con'sflantzand continuous treatment.

If the hot cottonseed press oalte from: the press is broken. u and ground and treated while still hot with a hot calcium chloride solution, the calcium chloride solution will act upon the hot meal BJlClCOmblRQtlJEI'QTW lIlI in a somewhat similar manner as' when the meal' is cooked or further heated arfte-r'the in corporation of the calcium chloride solution therewith. Where a. more intimate combination of the calcium chloride with the meal constituents is desired, the treated meal containin the calcium chloride solution may be en jected to a further heating or cooking operation.

The treatment of the cottonseed meal in the manner above described results in the production of an improved stock food as compared with the untreated meal. The treated meal has shown a much higherfeeding value than the untreated meal made at the sametime from the same seed that is, the animals fed with the treated meal show ed a higher gain per lb. of cottonseed meal l'ed than those to which the untreated meal was given.

The calcium chloride appears to combine with or to change certain of theconstituents of the menlmuchias those having tonic prop.- erties, and the treated meal appears to have lostcompletely or to a considerable extent the toxic properties of the untreated meal. It is especially advantageous that this parthat or complete neutralization of toxic action is accompanied by the addition to the meal of a valuable feeding constituent, namely, a mineral calcium salt.

Among the other advantages which the treatment Withcalcimn chloride brings about are a preservation of the meal and a regulated moisture content.
